Abstract
A field experiment was conducted at the research field of HSTU, Dinajpur during November 2019 to March 2020 to find out the effect of irrigation frequency on the growth and yield of Soybean (Glycine max L.) cv. BARI Soybean-6. The experiment was carried out with a RCBD with four replications of irrigation treatments viz, I0= no irrigation (control), I1= one time at 20 days after sowing (DAS), I2= two times (20 and 40 DAS), I3= three times (20, 40, and 60 DAS). At 105 DAS the highest plant height (52.53 cm) was found from I2 treatment and the shortest plant (45.82 cm) from I0 treatment. The highest (5.91) leaf area index was obtained from the treatment of three irrigation (I3) at 90 DAS and the lowest (5.1) leaf area index from the control (I0). At the 90 DAS highest nodule number (9.208) and the lowest nodule number was (6.459) recorded from I3 and I0, respectively. The highest (90.09 g) fresh weight was obtained from the treatment I2 at 90 DAS and the lowest (65.64 g) was recorded in I0. I3 produced the highest amount of dry matter of (29.50 g) and the lowest amount of dry matter production at harvest (20.67 g) in I0 treatment. The highest seed yield was observed from I2 (1.638 t ha-1 ) which was statistically similar with I3 whereas, the lowest obtained from I0 (1.075 t ha-1 ). The highest small stover yield was obtained from I3 (1.759 t ha-1 ) which is statistically similar to I2 (1.754 t ha-1 ) whereas the lowest was observed from I0 (1.540 t ha-1 ) which was statistically similar to I1 (1.566 t ha-1 ). The highest biological yield was found from I2 (3.425 t ha-1 ) which is statistically similar to I3 and the lowest was obtained from I0 (2.56 t ha-1 ). The maximum harvest index was found from I2 (47.71 %) and the minimum was obtained from I0 (40.81 %). I2 treatment showed more significant results than the other treatment I0, I1 and I3. So, two times irrigation showed significant effect showed the highest yield of 1.638 t ha-1.
2019年11月至2020年3月,在迪纳杰浦尔HSTU研究基地进行了田间试验,研究了灌溉频率对大豆(Glycine max L.)生长和产量的影响。巴里Soybean-6。采用RCBD进行4个重复的灌溉处理,即I0=不灌溉(对照),I1=播后20天1次(DAS), I2= 2次(20和40 DAS), I3= 3次(20、40和60 DAS)。105 DAS时,I2处理株高最高(52.53 cm), I0处理株高最低(45.82 cm)。在DAS 90时,三次灌溉处理(I3)的叶面积指数最高(5.91),对照(I0)的叶面积指数最低(5.1)。90 DAS时,I3和I0的结节数最高(9.208),最低(6.459)。处理I2在90 DAS时鲜重最高(90.09 g),处理I0鲜重最低(65.64 g)。I3处理收获时干物质产量最高(29.50 g), I0处理收获时干物质产量最低(20.67 g)。I2籽粒产量最高(1.638 t ha-1),与I3相近,I0籽粒产量最低(1.075 t ha-1)。小秸秆产量最高的是I3 (1.759 t ha-1),与I2 (1.754 t ha-1)相似,最低的是I0 (1.540 t ha-1),与I1 (1.566 t ha-1)相似。I2的生物产量最高,为3.425 t ha-1,与I3相似,I0的生物产量最低,为2.56 t ha-1。I2收获指数最高(47.71%),I0收获指数最低(40.81%)。I2处理比I0、I1、I3处理效果更显著。因此,两次灌水效果显著,最高产量为1.638 t ha-1。
